Title: Fluid pressure operated motor
Inventor: WARR ROLAND ARTHUR
IPC: F01C1/08
Filed: 1986-04-14
Abstract: Formed within the motor housing 4 is a helical recess 6 which forms with the surface of a cylindrical rod 1 a helical chamber. Carried by the rod 1 is a radial projection 9 which slidably engages in the recess 6. The housing 4 has ports 7, 8 through which a fluid pressure differential can be applied in the helical chamber across the projection 9 to displace that projection along the helical recess and thereby impart simultaneous axial and rotational displacement of the rod 1 relative to the housing 4. The helical recess 6 may be formed by a helical preform secured within a cylindrical bore of the housing 4 and the projection 9 may be a component secured to the rod 1. In an alternative arrangement the helical recess can be formed on the rod 1 by a helical preform secured thereto while the radial projection is carried to project from the bore of the housing and engage in the helical recess. <IMAGE>

Title: Hydroelectric apparatus
Inventor: MCCULLOCH MARTIN LINDSAY
IPC: F03B13/26
Filed: 1986-10-28
Abstract: Hydroelectric apparatus including a high level reservoir 13, a conduit 14 leading to a lower point and a turbine 16 for generating electricity in the conduit is improved by the provision of a low level reservoir 15 for containing the water downstream of the turbine.

Patent GB-2199000-A (GB)
Title: A valve assembly for a power assisted steering system
Inventor: ADAMS FREDERICK JOHN
IPC: B62D5/083
Filed: 1986-12-19
Abstract: The imput shaft (2) has a valve rotor (3) received in a valve sleeve (16) of the output shaft (5) and relative rotation between the rotor (3) and sleeve (16) from a neutral condition of a valve which they form controls fluid flow for power assistance. A torsion rod (7) extends between the shafts (2) and (5) to bias the rotor (3) and sleeve (16) to the neutral condition. Secured on the shaft (5) for rotation therewith is a carrier (10) within radial bores (12) of which are mounted balls (14) that are radially displaceable in response to fluid pressure thereon to engage in seats (13) in the shaft (2). As fluid pressure on the balls (14) increases they are urged into engagement with the shaft (2) to restrain relative rotation between the shafts (2) and (5) for reducing power assistance which is available. The sleeve (16) is initially coupled through sliding surfaces (17, 18) to the carrier (10) so that, on setting up of the valve, the sleeve (16) can be rotated relative to an optimum position of engagement between the balls (14) and their seats (13) to ensure that the valve is in its neutral condition. Following such setting up the surfaces (17, 18) are secured for example by welding, bonding, peening or pinning. <IMAGE>

Title: Activating a missile
Inventor: BERTHOLD RAINER
IPC: F42C13/04
Filed: 1987-07-06
Abstract: After the launch of a flying station. e.g. a missile, its distance from a base station, e.g. a tank, is continuously detected and compared with a stored distance between the base station and the target; if the two values coincide, the flying station is activated. The invention compensates for the perturbing effect of base station and target movements by determining the velocities of these at the base station and adjusting the frequency the microwave signal which is transmitted to the flying station for generation of a Doppler signal. A subtraction circuit forms the difference between the target velocity and the tank velocity. The product of the frequency of the generator on the launch of the flying station (50) and the output signal of the subtraction circuit is formed by means of a multiplier. From the voltage signal of the multiplier and a voltage signal proportional to the speed of light a divider generates a voltage signal with which the frequency of the generator is controlled.

The switching assembly comprises a magnetic flux diverting element 4 which is sandwiched between two ferro-magnetic pole pieces 5, 6, and is arranged to facilitate or hinder the passage of flux from the flux producing assembly to the workpiece attracting surface according to the rotational position of the diverting element relative to the flux producing assembly. The flux producing assembly comprises a magnet 1 sandwiched between two ferro-magnetic pole pieces 2, 3, whereby when the magnet and the diverting element are aligned the flux passing to the workpiece attracting surface is at a high value and is progressively reduced on relative rotation of the two assemblies. The flux diverting element may comprise a non-magnetic element, or a magnet. <IMAGE>

Title: Screen for printing electrical circuits
Inventor: WALTON BRIAN
IPC: H01L21/48
Filed: 1988-02-05
Abstract: A printing screen, particularly for use in the printing of electrical circuits, comprises a metal foil (1) having an array of holes (2) etched through it, and a layer of a screen printing emulsion (3) applied to one surface of the foil.

The foil may be mounted indirectly in a printing frame by bending the foil to a woven mesh stretched in conventional fashion on the frame and then cutting away the mesh in the general area of the pattern. If a suitably resistant emulsion is used then the etching of holes into the foil may be a later step than the pattern formation in the emulsion. <IMAGE>

Title: Optical transmission process and system
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/50
Filed: 1989-10-24
Abstract: In a frequency shift keyed direct detection (FSKDD) optical transmission system, an optical carrier 14 is frequency modulated with a higher frequency part 16 of an input signal. The frequency modulation is converted in an optical frequency discriminator 18 (eg Mach Zehnder or Fabry Perot interferometer) to an intensity modulation and the carrier is further intensity modulated with a lower frequency part 17 of the input signal, eg by phase modulating the discriminator. The doubly modulated carrier is then transmitted to a receiver station for demodulation and recovery of the original signal. The technique overcomes the problem of poor low frequency response of semiconductor injection lasers. <IMAGE>
